Allen-Bradley 1606-XLS480F-3 48V 10A Three-Phase PSU
Product Introduction
The 1606-XLS480F-3 is a performance-class power supply from the Allen-Bradley Bulletin 1606-XL series. Rockwell built this three-phase unit for demanding industrial applications that need a stable 48V DC rail. Specifically, it combines high efficiency, a generous power reserve, and compact dimensions. Engineers commonly deploy it in machine control cabinets, process automation panels, and material handling systems where 48V loads and reliability matter.
Technical Specifications
The 1606-XLS480F-3 accepts a three-phase AC input spanning 380 to 480 V nominal. Output is 48 V DC nominal, adjustable across 48 to 55 V. At 48V the unit supplies 10 A nominal, and the current range tapers from 10 A to 8.7 A as voltage rises. Rated power sits at 480 W.
Efficiency reaches 95.4% typical, which limits heat buildup inside enclosures. Ripple and noise stay at 100 mV maximum across the 20 Hz to 20 MHz band. Furthermore, a 50% power reserve supports short-term peak loads without shutdown. A DC OK relay contact provides remote status monitoring.
Spring terminals simplify wiring and reduce installation time. Additionally, the output is adjustable via a front potentiometer. Approvals include UL 60950-1, cUL, and CE marking under the official Bulletin 1606 series standard.
No communication ports or protocols exist on this device. Specifically, it is a pure power conversion unit with relay-based status signaling only.
Mechanical and Environmental Parameters
Dimensions measure 124 mm (H) × 65 mm (W) × 127 mm (D), and the unit weighs 870 g. Housing is a DIN rail mount construction rated IP20. Operating temperature spans -25 to +70 °C, while storage tolerates -40 to +85 °C. Relative humidity ranges from 5 to 95% non-condensing.
Installation Guide
First, mount the 1606-XLS480F-3 on a standard DIN rail inside the control enclosure. Next, connect the three-phase input wiring and confirm the voltage falls within 380 to 480 V AC. Then set the adjustable output to the required level using the front potentiometer. Meanwhile, connect the DC OK relay contacts to the monitoring circuit. Finally, use the spring terminals for load wiring, verify the output voltage after power-up, and check for short circuits before applying full load.

FAQ
Q1: What output voltage range does this supply offer?
A: It provides 48 V DC nominal, adjustable from 48 to 55 V via the front potentiometer.
Q2: How much current is available at 48V?
A: The unit delivers 10 A nominal at 48V, derating to 8.7 A at higher settings.
Q3: What does the 50% power reserve mean?
A: The supply can deliver short-term peak power well above its 480W rating without shutting down.
Q4: Does it include a communication port?
A: No. The 1606-XLS480F-3 has no communication interface; status signaling uses a DC OK relay contact.
Q5: Is the 1606-XLS480F-3 still active?
A: Yes. Rockwell lists it as active in Bulletin 1606-TD002H (July 2023) technical data.
